Image Circles on Wide Lenses- what's what?greenspun.com : LUSENET : Large format photography : One Thread
I'm choosing a wide angle lens for my 'point-and-shoot' 8x10...So far experiments have indicated that the Nikkor 4.5 has the most effective useable image-technically the circle is 235. But specs say the f8 has an equivalent circle-NOT...What about the 5.6 Super Ang? or 5.6 Fujinon?...Anyone know? Thanks.

When you consider the HOBO cameras advertise mounting the Wide angle 120 Nikkor, you know they will cover and the cost isn't too high. If you go with a longer lens than the 120 you have a lot more to choose from.

Dan- Thanks for contributing a very reasonable solution...While my implication was that coverage is everything - it's not. I want the 90 with the largest circle- I already have the camera...a 120 would necessitate a 2"deeper box and inhibit the 'universal' focus...the con venience of this device is amazing and it 'feels' right to me in this configuration- I just want to use it to its best advantage.

Relying on the manufacturers' specs, the 90 mm lens with the largest coverage would seem to be the Schneider Super-Angulon XL, with a 259 mm image circle.

Check those Nikkor specs carefully. Nikon quote the image circle at different apertures for the f/4.5 and f/8 lenses in their brochure.
